The Erdos Paradox 8 years ago
Somebody launch the Journal of Low Hanging Fruits: an interdisciplinary journal where people from the research field A pick the low hang hanging fruits from research field B, using knowledge from A. And, conversely, people from B reply by showing those from A that their most cherished result should have been discovered earlier, because is a trivial application of an old technique from B.
In mathematics this happens all the time, but there is no dedicated place for this show.
